Using Powdered Milk to Cut the Food Budget
Cultured Buttermilk: You can make your own buttermilk at home, from reconstituted powdered milk. You will need commercial buttermilk as a starter. Mix up a quart of reconstituted milk by combining 3 3/4-cup water with 1 1/3 cups dry milk powder. Add 1/2 cup of fresh buttermilk, purchased from the store. Allow it to sit on the counter overnight.
